VALVE CONSTRUCTION.

parts. The solution for this problem has The lOOCly 12 iS als@ plOVded'Will e nnln been found in eliminating the large single ber OfllIlObStlnCted ports 1S, su'iiloient in moving valve element andsubstituting a lie aggregate. t0 Cere for the maximum pos- 'number ofsmall ports, and cooperating sible flow through the Openings 8 past l)valve elements, each of which need have an VelVeS l0- Tlle Shell v01Cylinder 19 may be lee extremely small movement, while the aggre-.provided substantially as shown, to extend gate valve port opening willbe ampie. for doi'vnwardlyand around the elements 6 and the maximumdemand of the pump. l l2 in order to protect the same.

To the end of the tube 5 is secured the In operation: shell or chamberedbody 6 by threaded en- -Vhen the tube 5 is reciprocated the fol- 110lowing action takes place: The lower end of this tube, it will beunderstood is immersed; upon its downward movement, the water passesthrough the ports 8, the valve elements 10 moving from their seats intothe housings 11, due to the force of the inrushing water. The waterpasses from ports 8 into space 16 thence through ports 18 upwardly intube 5. lhis action continues during` the downward movement of tube 5.Upon the reverse movement of tube 5, that is, the upward movement oftube 5, the water .Within the tube will normally cooperate with theelements 10 to cause them to seat Von their respective seats 9, so thatno water can flow from tube 5 bach to the well. It will be noted thatthe movement of each element 10 from open to closed position and viceversa, is extremely short and that therefore there is practically nomomentum, or shock, or jar upon the reversal of the tube 5, and yet theaggregate of the openings controlled by the valve elements, is such asto permit a comparatively large volume of flow upon the downstrolre oftube 5. As this movement is short and is distributed through a. largenumber of valve elements, it follows that there is practically noinertia, as of a large body, to overcome and the opening and closing ofthe ports 8, are, as a result, eX- tremel';7 rapid.

lt happens that, due to the momentum of the column of water traveling upthrough pipe 5, the water continues to travel upwardly after themovement of pipe 5 is reversed, that is, after it begins to descend. Ifthe reciprocating movements are suliiciently rapid, there may be acontinued upward movement of water through pipe 5. The upward strokestherefore tend merely to boost oraccelerate the vupward flow. ln suchcase, the valve elements open only when the pressure outside the ports 8is greater than the pressure inside said ports. When these pressures areequalizcd-the valves close bv the action of gravity.

It will be understood however that the action of the valve elements isnot necessarily dependent upon a reciprocating movement of the bodycontaining the ports and valve seats with wiich the valve elementscooperate The construction is equally applicable to a stationarystructure containing a valve controlled chamber, in which there is avariation of pressure within said chamber. Devices of'this class aredescribed in a. number of patents to Humphrey, for reciprocating columnpumps, for example, Patent No. 1,037,009 dated Aug. 27, 1912 and PatentNo. 1,243,296 dated Oct. 16, 1917. In these pumps a column of water ismade to reciprocate in a stationary play pipe; the initial movement ofthe outstroke being caused by the expansion of a primary medium. The

momentum of the water column, after the normal expansion of the primarymedium, causes a diminution of pressure to the rear of the column whichin turn causes the introduction of fresh water through a non-returnvalve structure. The return stroke of the water column and the force ofthe momentum thereof is utilized in compressing a fresh primary charge.rEhe rise in pressure resulting from the return stroke also causes theclosure of the non-return valve or valves. Vhere the valve comprises alarge moving part, considerable time is required to cause the closure,and the force of the moving volume of water also causes considerableshock to the moving parts. It will thus be seen that the construction inaccordance with the present invention is admirably adapted for theconditions last above recited, and for overcoming the obiectionsreferred to.

What I claim is 1. In avalve construction, the combination of a shellformation provided with a plurality of apertures extending through thewall thereof, said apertures having valve seats associated therewith,ball valves adapted to cooperate with said seats, and means surroundedby the said shell formation providing housings independently thereof forsaid ball valves.

In a valve construction, the combination of a conical shell formationprovided with a plurality of apertures extending through the wallthereof, said apertures having valve seats associated therewith, ballvalves adapted lto cooperate with said seats, and means surrounded bythe said shell formation providing housings independently thereof forsaid ball valves.

3. In a foot valve, the combination of a pairof shells, one positionedwithin the other, each shell provided with a plurality of ports, theports of the outer shell provided with valve seats and the inner shellprovided with housings for valve elements, and valve elements adapted tomove to and from the valve seats.

4. In aV valve construction, the combina.- tion of a pair of shells, onepositioned within the other, each shell provided with a plurality ofports, the ports of the outer shell provided with valve seats and theinner shell provided with housings for valve elements, and valve ballelements adapted to move to and from the valve seats. Y

5. In a valve construction, the combination of a pair of shells, onepositioned within the other, each shell provided with a plurality ofports, the ports of the outer shell provided'with valvel seats and theinner shell provided with housings for valve elements, valve elementsadapted to move to and from, the valve seats, and means for assemblingthe shells to secure proper register between the respective housings andvalve seats.

6. ln a valve construction, the combination of a pair of ohamberedformations one formation projecting into the other, each provided with aplurality of ports, the ports of one formation registering substantiallywith the ports of the other formation, one formation provided With valveseats surrounding its ports, the other formation provided With valvehousings Communicating with its ports, and valve ball elements movablein said housings to and from Said valve seats.

7. In a reciprocating valve structure, the

combination of a pair of ohamloered forma- 15 tions one formationprojecting into the other, each provided with a plurality of ports, theports of one formation registering substantially with the ports of theother formation, one formation provided with valve seats surrounding itsports, the other formation provided With valve housings inclined to thehorizontal and communicating Withits ports, and valve ball elementsmovable in said the structure, to and from said valve seats.
